 Coir mix and pasteurize ?'s 
#11473473 - 11/17/09 02:19 PM (3 years, 6 months ago) |

I've been searching around the forums quite a bit on spawning to coir. I just have a couple of questions.
The mix i'm gonna use is 15% coffee 15% vermiculite 5% gypsum from drywall and 65% coir. Is this a good ratio or would you guys suggest something else?
I would like to be as safe as possible so i'm going to be pasteurizing my mix. I was thinking of put the mix in oven bags then heating in the oven on 160 degrees for 2 hrs. Is that sufficient enough?
Lastly I ordered rye berries to use as spawn but I also have a lot of brf, would using brf as spawn work out ok?
Thanks a lot everyone!

Can't really comment on this, seems ok to me, it's just that i use 100% manure or 90 / 10 % manure / verm.

Using the pillowcase method is efficient. check my sig for an explanation of the procedure.

Using brf can work, you can make pf cakes and spawn them to bulk. Try wild bird seed or rye grain as well. These subs are popular and provide the most much it seems If you use the rye berries as spawn you'll get more mush. I'd advise against using 100% brf because I haven't seen many people using that and i don't know if the results are consistent enough.
Thanks a lot everyone!

BRF contams easily. I only see people using it with BRF cakes.

'oven pasteurization' has been debunked... I think RR often writes that it doesn't work.
Grain is most often used to spawn to bulk, though BRF is sometimes used successfully too - usually with a food processor, cheese grater, or just plain crumbled up in bags. The smaller the better...

Crumbling in bags works fine, especially when you crumble relly well. A cheese grater is overkill IMO. Also, I don't get how people can't get pf cakes to spawn.

I've read that pasteurizing using the pillow case method can cause the coir mix to lose nutrients. Is there any truth to that?

I don't know, but most people just throw boiling water into a bucket, cover it, and let it sit overnight. they then squeeze out excess moisture from the coir and then mix it up.
So you going to monitor your temps closely or throw water into a bucket?

Yea I guess thats a good point  .
Well should I just sterilize the coffee grounds gypsum and vermiculite then add them to the coir after I let it cool down over night?

Exactly. Or, if you have a meat thermometer heat the water to about 180degrees, add water to 5gallon bucket, and wrap a blanket around the bottom of the bucket if you think it is necessary. Use/mix this bulk sub 12 hours later.
Who the hell is recommending to pasteurize coco-coir in a pillowcase?
I wear gloves while mixing up the bulk substrate. Once you get a good eye for the coir you won't need to squeeze every handful to ensure you're at field capacity.

No. You should pasteurize these additions to your bulk substrate than add them to the bucket of coir. If you're going to use coffee grounds you need to pasteurize exactly as directed in a good tek and not sterilize your entire bulk sub.
If you are tight on space to pasteurize the additions to your coir you can skip pasteurizing the vermiculite altogether, and instead simply hydrate it separately with some really hot water before adding it to the coco-coir.
Best of luck! ~P~

Quick bump to see if anyone else has input on my ratio?
Thanks a lot for all the help!

Your ratio is fine, but pasteurization occurs when the substrate temperature is maintained at 140F/60C for 90 minutes. If you use a 160F oven, it might take 12 hours or longer for the substrate to heat to that temperature. I'd suggest putting the substrate into bags or jars and heating them in a pot of water on the stove. You can see an example of it done that way in video format on my website in the horse manure or casing tek.

Can't thank you enough.
Using your tek on my rye berries and will definitely watch your video!
Thanks again everyone for being such a help!
